This is a jousting helm that I am modeling. Is missing a couple of details, and final texturing and showcasing, so these are basically tests to see how it is coming along.
This are the default, Luxrender settings for Shinny Metal and Gold. I will eventually adjust the materials. As for the number of stars, original jousting helms had all of these; they are there not just for ornamental purposes, but were the rivets that kept the helm together.
good work. Lux is an AMAZING engine. I am using lux for my lamborghini model. You may want to put firefly rejection up to 5 or so. not much higher cuz it will kill your ram. This can be found in the bottom of your cameras settings, not to be confused with render settings.
